You can apply. But I want to remind you that if you have the same bank card, the quota is shared. In other words, if the credit limit of your previous three cards was 3,000, the credit limit of this card is 3,000 now, and the credit limit is not increasing. If you want to increase the quota, you'd better choose other banks to handle it, or you can issue these cards at CCB. As long as there is no bad record, it will generally help to apply for a card.
